Hi all,
       The below statement is taking a very long time, can any one please suggest what can be done to reduce the time.
*read PO history from EKBE join EKKO
SELECT ekbeebeln ekbeebelp ekbe~vgabe
  ekbegjahr ekbebelnr ekbebuzei ekbebewtp
  ekbebwart ekbebudat ekbemenge ekbedmbtr
  ekbewrbtr ekbewaers ekbearewr ekbeshkzg
  ekbecpudt ekbexblnr ekbematnr ekkolifnr ekpo~meins
INTO TABLE l_tbl_ekbe
FROM ekbe JOIN ekko
   ON ekbeebeln = ekkoebeln
JOIN ekpo
    ON ekbeebeln = ekpoebeln
   AND ekbeebelp = ekpoebelp
WHERE ekbe~ebeln IN s_ebeln
   AND ekbe~ebelp IN s_ebelp
   AND ekbe~vgabe IN r_vgabe
   AND ekbe~gjahr IN r_gjahr
   AND ekbe~budat IN s_budat
   AND ekbe~matnr IN s_matnr
   AND ekbe~werks IN r_werks
   AND ekko~bukrs = p_bukrs
   AND ekko~lifnr IN s_lifnr
   AND ekko~bsart IN r_bsart.
*Select History per Purchasing Document: Delivery Costs (EKBZ)
  REFRESH l_tbl_ekbz.
  SELECT aebeln aebelp a~vgabe
  agjahr abelnr abuzei abewtp
  abudat amenge a~dmbtr
  awrbtr awaers aarewr ashkzg
  acpudt axblnr c~matnr
  blifnr cmeins
  a~belnr AS awkey
  FROM ekbz AS a JOIN ekko AS b
      ON aebeln = bebeln
      JOIN ekpo AS c
      ON aebeln = cebeln
      AND aebelp = cebelp
  INTO CORRESPONDING FIELDS OF TABLE l_tbl_ekbz 
  FOR ALL ENTRIES IN l_tbl_ebeln
  WHERE a~ebeln = l_tbl_ebeln-ebeln
      AND a~ebelp = l_tbl_ebeln-ebelp
      AND a~budat IN s_budat.
  APPEND LINES OF l_tbl_ekbz TO l_tbl_ekbe.

Hi,
Use INNER JOIN rather than JOIN.
And change the join structure, first take on left EKKO, EKPO then EKBE.
Same way for second query EKKO, EKPO then EKBZ.
Hope this will increase performance.
